HEIC, animated WebP input, PNG sequences and frame sequence export require Pro.

WebM and WebP are cousins — both born from the same codec family, both built for the web — but they behave very differently in a page. A WebM is a video: it needs a video element, playback rules, and sometimes a user gesture before it moves. An animated WebP is an image: put it in an image tag and it simply plays, loops, and never shows a control bar. Converting WebM to WebP is how you turn "a video I have to embed" into "an image that happens to move".

That distinction matters most for hover previews, hero loops, tutorial snippets in docs, and anywhere autoplay policies or CMS restrictions make video embedding a fight. Screen recordings that browsers export as WebM — Loom-style captures, browser dev-tools recordings, Discord clips — convert especially cleanly.

Upload the WebM, trim to the loop you want, set fps and quality, and download. The conversion runs server-side on FFmpeg with no signup, no watermark, and automatic deletion of your files about an hour later.

Why convert with LightBox

Autoplays as an image, everywhere

Animated WebP sidesteps every autoplay policy, because to the browser it's just an image. No muted-attribute dance, no play button appearing on mobile, no CMS stripping your video tag. If you've ever fought WordPress or Notion to make a clip loop inline, this is the fix.

Right-sized for the job

A hover preview doesn't need 1080p at 30 fps. Resize to the rendered width, drop the frame rate, and trim to a clean loop — the result is often a tenth of the original's size, which keeps your page snappy and your Core Web Vitals green.

Keeps WebM's alpha channel

If your WebM carries transparency — a common trick for animated UI elements — animated WebP preserves it with full 8-bit alpha. That's something GIF fundamentally can't do, and it makes WebP the only sane target for transparent animations headed to a web page.

Frequently asked questions

Keep WebM when the clip is long, needs sound, or benefits from player controls — it's a real video format and compresses long content far better. Convert to animated WebP when the clip is a short, silent loop that should behave like an image: autoplay, no controls, no fuss.

No — animated WebP is an image format, so any audio track is dropped automatically. If you need the sound, stay with WebM (you can still trim, crop, and compress it here) rather than converting to an image format.

Yes. Animated WebP supports a full 8-bit alpha channel, so transparent WebM clips convert with their soft edges intact. That makes it ideal for floating UI animations, stickers, and overlays — a use case where GIF's all-or-nothing transparency falls apart.

Use the trim controls to cut the clip so the last frame flows into the first — even trimming a few tenths of a second off each end often does it. The loop count control then sets whether it repeats forever (the default) or plays a fixed number of times.

Yes — free, no watermark, no signup, files up to 100 MB, auto-deleted after about an hour. If you convert screen recordings all day, the one-time Pro upgrade adds batch conversion, presets, a permanent library, and 1 GB uploads.
